摘要： A lighting unit is incorporated in an LC display. The lighting unit includes a light guide and a light source adjacent to the light guide. The light guide includes a rear surface facing an LC panel, a front surface opposite to the rear surface, a first side surface between the rear and the front surfaces, and a second side surface spaced widthwise from the first side surface. The light from the light source travels into the light guide, and from the first toward the second side surfaces. A reflector for reflecting the light incident on the second side surface toward the first side surface is formed on the second side surface. The front surface of the light guide is formed with first and second slant portions. Each first slant portion reflects the light, traveling from the first toward the second side surfaces, toward the rear surface of the light guide. Each second slant portion reflects the light, traveling from the second toward the first side surfaces, toward the rear surface of the light guide.
